Re: COMP_zlibd don't return a valid method

[prakash babu]

Hi Ignacio ,

 

I think that the problem is that your are not linking the appropriate libraries.

Try the following steps

 # ./config zlib
 #  gmake
 #  gcc test.c -L<OpenSSL Source Directory> -I<OpenSSL Source Directory/include> -lssl -lcrypto -lz -ldl
 #./a.out
 compression name: zlib compression

Your Method

#gcc test.c -lssl -lcrypto

//this will use the crypto and ssl libraries that comes OS which is present in the /usr/lib directory and this may not be built with zlib support

# ./a.out
compression name: (null)

Thanks,

Prakash

hi,

well, i'm using Linux, with a 2.4.xx kernel and the 0.9.8 version of
the ssl library,

to compile it i do: gcc -o master master.c -lssl -lcrypto -lpthread
(same as you do it)

i've compiled the library configurating using "./config zlib" the
library is compiled with this parameter...

thanks prakash,
ignacio
